So I ported my intake manifold for the 60mm TB's. Kept most of the debris out, but have some stuck to the oil film inside. The plenum is powdercoated and my powdercoat guy recomends NOT using a parts washer due to the staining that may occur. Just wanted to see what anyone else does, since theres some tight spots. My only thought was brake clean with the straw followed by washing with water after.
